Part 6: The "Best" Compromise – Buying Old Navionics Cards

If you insist on the real Navionics interface but don't want to pay full retail, go to eBay or Facebook Marketplace.

Search for "Navionics HotMaps" or "Navionics+ SD Card – used."

Price: $30 – $80 (vs $200 new).
The catch: The card may be 2-3 years old. You cannot update it without paying a "FreshMap" update fee ($99).
Hack: Buy an old card, then use Navionics' Chart Installer on your PC. Sometimes, the software allows you to refresh the region for a reduced "legacy upgrade" price ($49).
